How to use the friendly serial port debugging assistant

​ ​ 1. After downloading and installing the Friendly Serial Port Debugging Assistant on this site, find the icon on the desktop and double-click to run it. The main interface is as follows:

​​ 2. First, select the baud rate based on the information sent from the serial port. This baud rate is selected according to actual needs. Ensure that the sending and receiving are consistent, otherwise the data may not be received. Sometimes it can be received, but it is all garbled.

3. According to the transmission protocol, set the data bit, check bit, and stop bit. These three also need to be consistent with the sending end. Generally speaking, the default setting is 8-N-1.

​​ 4. After connecting the hardware, select the transmission port, corresponding to the USB port on the computer

5. Set the data sending and receiving mode and choose according to actual needs

​​ 6. Click "Run" to send and receive data packets

​​ 7. The serial port debugging assistant can also debug TCP/UDP data packets. In the figure below, its usage is similar to the former.

Comparison of similar software with Friendly Serial Port Debugging Assistant

​​​1.Serial debugging assistant

Advantages: Easy to use, largest user base, book introduction and free source code.

Disadvantages: 1) Due to the use of multi-threaded receiving technology, data is sometimes lost when receiving, especially at high baud rates or when using USB to serial port.

​ ​ ​ 2) Only supports 115.2K baud rate.

Frequently Asked Questions about Friendly Serial Port Debugging Assistant

Serial port parameters do not match:

Check whether the serial port parameters set by both parties are consistent, including baud rate, data bits, check bits, stop bits, etc. Make sure these parameters are exactly the same on the sending and receiving ends.

If you are not sure about the parameter settings of the other party's device, you can try different parameter combinations for testing.

Serial port voltage mismatch:

Different serial port devices have different high and low level thresholds that can be decoded normally. For example, for the same 3.3V serial port communication, the low-level threshold of device A may be 1.5V, while the low-level threshold of device B may be 1V. When the actual low level of the serial port voltage is only 1.5V, device B may not be able to receive data normally.

Check and confirm the voltage compatibility of the serial device and use level conversion circuits if necessary.

Actual baud rate deviation:

There may be deviations between the actual baud rate of the serial port and the theoretical value. For example, when the nominal speed is 9600bps, the actual operation may reach 10000bps (the error exceeds 4%), which may cause the receiver to be unable to decode correctly.

Use a tool such as an oscilloscope to measure the actual baud rate and compare it with the set value. If the deviation is large, try adjusting the settings on the sender or receiver.
